“- THE GROUND STRAP CORRODED AND BROKE APART. YES, I HAVE THE GROUND CABLE THAT FAILED, IF NEEDED FOR INSPECTION. - YES!!! THE TRUCK'S STEERING KEPT GOING IN AND OUT OF MANUAL STEERING AND THE ENGINE REDUCED IN SPEED ALLOWED, AND THEN THE ENGINE CUT OUT ON ME COMPLETELY - WHILE I WAS IN THE MIDDLE OF A BUSY ROAD TRYING TO TURN ONTO A SIDE STREET. THEN THE ENGINE WOULD NOT RESTART. - I HAD THE TRUCK TOWED ON A FLAT BED TO A GMC DEALERSHIP NEARBY. THEY CONFIRMED THE ISSUE WAS THAT THE GROUND STRAP FAILED. THEY REPLACED THE PART AT MY COST, WHICH FIXED THE ISSUES. - YES, THE DEALERSHIP INSPECTED AND CONFIRMED THE ISSUE WAS THE CORRODED AND BROKEN GROUND STRAP. - YES, THERE WERE MANY WARNING MESSAGES THAT STARTED TO APPEAR ABOUT 3-4 DAYS PRIOR TO THE COMPLETE FAILURE OF THE ELECTRICAL SYSTEM. I STARTED SEEING A MESSAGE ABOUT SERVICING THE TRAILER BRAKE SYSTEM, AND ANOTHER ABOUT SERVICING THE SIDE DETECTION SYSTEM. THEN A SERVICE POWER STEERING WARNING AND TO DRIVE WITH CARE. THE CHECK ENGINE LIGHT WAS OFF AND ON OVER THAT TIME. - I CHECKED THE WIRE CONNECTIONS IUNDER MY VEHICLE TO CHECK FOR BROKEN WIRES OR CORROSION. I DID NOT FIND ANY. I THEN CHECKED IF A HARD BATTERY RESET WOULD WORK, BUT IT DID NOT. LASTLY, I BOUGHT A NEW BATTERY TO REPLACE THE EXISTING ONE, EVEN THOUGH THE EXISTING BATTERY HAD NO ISSUES EVEN WHEN TESTED UNDER LOAD. THAT RESOLVED THE ISSUE FOR ABOUT 35 MINUTES THAT NIGHT AND THEN THE NEXT MORNING. AFTER THAT, THE ELECTRICAL SYSTEM FAILED AND THE TRUCK WOULD NOT START. AT THAT POINT I GOT TOWED IN TO THE GMC DEALERSHIP. I HAD TO LEAVE THE TRUCK FOR A WEEKEND, AND THE DEALERSHIP DID NOT COME UP WITH A LOANER, EVEN THOUGH I REQUESTED ONE. I GOT THE TRUCK BACK ON MONDAY AFTERNOON AND EVERYTHING WAS WORKING FINE SINCE THEN. - OVER THAT WEEKEND, I WAS AMAZED TO FIND OUT ABOUT THE BULLETIN GM RELEASED TO COVER ONLY SOME TRUCKS FOR THE ISSUE, BUT NOT OTHERS! MY TRUCK IS STILL NOT COVERED, DESPITE THE OBVIOUS SAFETY ISSUES I EXPERIENCED!!”

“A known problem with these trucks is ground strap failure. I was driving and all the sudden lost power steering which almost caused an accident. There is a customer satisfaction program N252515590 that covers 2019-2024 trucks but mine was not included in this for some reason. I did have the truck fixed a my cost and was looking to get my money back from GM. I'm not sure if you can help with this but wanted to make a report that is happening with more trucks then they are fixing. If you need any other info from me please let me know”
